3. The combination with a disc harrow embodying spaced discs and an axle inclined to the line of travel, a member secured to the axle and extending rearwardly of the disc and provided with a bend, a beam pivoted to the member adapted to swing in a horizontal and a vertical plane, a quadrant pivotally connected with the barrow structure, a manual lever pivotally connected with the quadrant, and links connecting the manual lever with the beam.

4. The combination with a disk harrow having a series of disks disposed at axial angles to each other, of a bearing carried by one of the series of disks and extending perpendicularly to the axis and continued by a rigid extension at an angle to the axis and substantially parallel with the line of travel of the harrow, a segment pivoted to swing in a horizontal plane relative to the bearing, a beam pivoted to the extension adapted to swing universally at a lever mounted for co-action with the segment; and a link connecting the lever with the beam;
